Parrot asks you to switch off your smartphone’s Wi-Fi connection when flying ANAFI Ai with both the Parrot Skycontroller 4 and your phone:
With this configuration, the drone and the controller communicate through ANAFI Ai’s Wi-Fi network and activating your phone’s Wi-Fi can only result in interferences.
Therefore, your phone’s Wi-Fi should only be activated – and connected to ANAFI Ai’s Wi-Fi network – when you want to fly the drone using your smartphone as its sole controller.
